UNITED STATES PATENT OFFICEQ JOHN B. DEEDS, F TERRE HAUTE, INDIANA,ASSIGNOR OF ONE-HALF TO ANDREYV GRIMES, OF SAME PLACE.

LAMP-BURNER AND CHIMNEY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 273,039, dated February27, 1883.

Application filed December 30, 1882.

To all whom it may concern: Be it known thatl, JOHN B. Bases, of TerreHante, in the county of Vigo, and State of Indiana, have inventedcertain new and useful Improvements in a Lamp-Burner and Chimhey-Holder;and I do hereby declare that the following is a full,clear, and exactdescription of the invention, which will enable others skilledin the artto which it appertains to make IO and use the same, reference beinghad-to the accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

This invention relates to that class of bydrocarbon-burners in which thechimney is mounted upon a perforated metallic plate, through which thewick -tube passes, and above which is arranged a deflecting-cone.

The objects of this invention are to keep 2 the base of the chimney frombeing overheated and broken off by consequent expansion or suddencooling; to provide a burner with a chimney-fastening device which willbe antomatically adjusted to the chimney-base, as

5 the latter expands or contracts, thereby obviating breakage from unduecramping, and at the same time securing steadiness and a firm holding ofthe chimney; to secure a copious supply of air to the flame and a strongup- 3 ward current alongside the wick-tube, thereby obviating theproduction of smoke and the deposit of soot upon the burner-plates andchimney, and to prevent the extinguishment of the flame by suddenair-currents entering the burner whenthe lamp is being carried fromplace to place.

In the accomplishment of these objects the invention consists in certainnovel constructions and combinations of devices, which will 4 behereinafter particularly described with reference to the accompanyingdrawings, in which Figure 1 is a view showing the burner partly invertical section in a plane indicated by the line w w of Fig. 2, thelower portion of the chimney in section, and the upper part of theoil-holder in elevation. Fig. 2 is a perspective view of the burner withthe main deflecting-cone removed. Fig. 3 is a View of the (No model.)

burner, mainly in vertical section in a plane at vright angles tothesection shown in Fig. 1.

Fig. 4 is a perspective View of the deflectingcone and its exteriordeflecting-rim. Fig. 5 is a perspective view of the air-guard.

Referring to Fig. l, the letter A designates the body or oil-holder ot'the lamp, and a is the internally-threaded collar into which thescrew-nipple b,Figs. 2 and 3, of the burner is screwed.

B is the perforated chimney-plate, which is open at the central portionandjoined to the wall of the casing or chamber 0, which surrounds thelower portion of the wick-tube'l), the bottom of which is secured withinsaid chamber, and the upper portion of which projects above thebase-plate, and issurrounded by the supplementary deflecting-cone E, andseparated therefrom byan air-passage, e. The wall of the chamber 0 isprovided with perforations c c, to admit air, which passes up throughsaid chamber and through the passage e, and is directed by the cone Etoward the wick and flame.

F is the main deflecting cone, having the the flame-passage, and whichis removably attached to the chimney-plate B,a-nd incloses the cone E,from which it is separated by an air-space, which is supplied with airthrough perforations p p in the chimney-plate outside of the cone E.Through these perforations and this air-space is supplied the main bodyof air which supplies the flame with oxygen in the usual manner, whilethe air passing through the supplementary cone E is designed to form astrong current or draft, which will carry the flame well up, and preventany tendency to smoke or to deposit soot or cinder about the base of theflame and top of the wick-tube.

Upon the extreme surface of the main deflecting-cone F, and near itsbase, is mounted an outwardly and upwardlyinclined deflectingrim, theofiice of which is to deflect cool air.

rising through perforations q q of the chimneyplate against the lower orbase portion of the chimney H, and thus prevent the same from becomingunduly heated and liable to breakage thereby or by sudden cooling whenthe flame 2 araoeo is extingushed or cool-air currents strike thechimney.

The main deflector F is removably secured in position upon thechimney-plate by means of attached flexible metallic fingers ff, whichare passed through apertures formed in the base-plate and clinchedunderneath said plate.

At the edge of the chimney-plate B is an upturned finger 'i, slightlyinclined inward, to prevent lateral movement of the chimney, and anoutwardly inclined finger, i, to the top of which a hinged curvedspring-latch,j, having a finger-piece or handle, K, by which it may beoperated. WVhen the chimney is properly located on the chimney-plate B,this latch is turned down upon the outwardly-projecting chimney-base, asshown in Fig. 1, and binds it to the chimney-plate with a yieldingpressure, thus permitting the chimney-base to expand without danger ofbreaking, while the spring-latch will also expand or extend itself byits resistence if the base contracts, and thus hold the chimney at alltimes steadily and firmly. When it is desired to remove the chimney, thelatch is thrown back, as shown in Fig. 2.

The letter L indicates an air-guard, consist ing of a circular metallicband, the upper edge of which is secured to the under surfaceof thechimney-plate B within the annular series of perforations q q andoutside of the perfora-.

tions pp, the lower edge of this guard being extended down below thechamber 0, which said guard surrounds. Air must pass under theguard L toreach the perforations c of chamber 0 and the perforations p of thechimney-plate, and thus said guard serves to prevent sudden lateralair-currents fromentering the burner and blowing out the flame when thelamp is exposed to the open air or is being carried from place to place.No provision is made to prevent air from passing through theperforations q, as such does not reach the flame on its first entrance,but is deflected against the chimney by the rim G.

The Wick-tube is provided with the usual feed-wheels, operated by theend or handle m.

I wish it to be understood that whileI have shown the deflecting-rim Gcarried by the main deflecting-cone F, I do not limit myself to sucharrangement, as said rim may be mounted directly on the chimney-plateand serve the same purpose that it does in the position shown in thedrawings.

I am aware that it is not new to form an air-passage between thelamp-chimney and a metallic plate, and therefore do not claim such,broadly.

Having now fully described my invention and explained the operationthereof, I claim 1. In a lamp-burner, the combination of thechimney-plate, having perforations within its margins, upon which thechimney rests, with 3. The combination, with the main deflect-.

ingcone having affixed thereto the circumferential deflecting-rim Gr,thechimney-plate having perforator p, and the wick-tnbe,of thesupplementary deflecting-cone E, and suitable means for directing asupply of air within said supplementary cone, substantially asdescribed, and for the purpose set forth.

4. The combination of the supplementary cone E and the wick-tube of thechamber U, having pelforations in its wall, with the airguard L,substantially as described.

5. The main deflecting-cone F, carrying the deflecting circumferentialrim G, substantially as described.

' 6. The main deflectingcone F, having the outercircumferentially-deflecting rim G and the flexible metallic fingersff,by which it may be removably secured to the chimney-- plate,substantially as described.

7. Thelamp-burnerconsistingofthechimneyplate having perforationsp and q,the chamber O, having perforations in its wall, the wick-tube having itslower portion in said chamber, the supplementary deflecting-cone E,surrounding the upper portion of the wick-tube, and the maindeflecting-cone F, carrying the deflecting rim G, the whole constructedand arranged substan tially as described.

In testimonythat I claim the foregoingas my own I affix my signature inpresence of two witnesses.

JOHN B. DEEDS.
